Serial No. 585,257.

The invention relates to electric contact in rail joints as described in the present speciflcation and illustrated in the accompanying drawings that'form part of this application.

The invention consists essentially in the construction, combination and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings.

The objects of the invention are to furnish in electrically connected rail lines contact members of higher conductivity than the rail metal thereby insuring a safe and positive electrical connection in rail joints, and to effect improvement in my pending application for electric connector in rail chair, Serial 569,106, filed June 17th, 1922.

In the drawings, Figure 1 is a perspective view of a rail joint showing the rail in cross section and broken away to disclose the contact members. 7

Figure 5 is a cross sectional view showing a section of rail base, copper contact mem- 0 ber, and base connector side strip.

Like numerals of referenceindicate corresponding parts in the various figures.

Referring to the drawings, the rail joint is formed on the base plate 11 having the rail recess 13 between the recess 1d and abutment 15. The copper plate conductor 16 is laid on the base plate 11 The bases 3 and 4 of the rails 1 and 2 are drilled at 5, 6, 7 and 8 and the rails are then placed on the copper plate 16 and the copper contact members, or plugs 9, 10, 11 and 12 are inserted in the holes 5, 6, 7 and 8 and hammered to a tlght fit. The copper plate 17 is thenlaid on the upper side of the base to one side of the web and over the copper contact members 9 and .10. The side strip 18'of copper is inserted in the bed of the recess 14 and over the copper contact members 11 and 12. The copper contact members 9, 10, 11 and 12'thereby make elec- Figure 4 is a perspective detail of a base these copper contact members maybe made in any other suitable shape "and'insertediin the base of the rail, the upper plate 17, and

the copper side strip 18. I

The joint plate 19 fits against the rail and extends outwardly over the rail base and? base abutment and completely covers the copper plate therebelow and the bolts 20 and V the nuts 21 fasten the said joint plate and copper conductor to the base 11 as well as closing in the filler key 22. v

In the use of this invention, the copper contact members are inserted in the holes drilled in the rail bases and swelled with a'hammer to a tight fit, and in the installation of the rail joint they are-bridged from rail to rail by, the copper plate connector. under. the rail base, by the copper side strip, and bythe copper upper connector over therail base, the whole being drawn tightly together by the. nuts and bolts through the joint plate. There is thus secured a reliable and positiveelec-t trical connection from rail to rail.

It is to be distinctly understood that the form and shape of contact member illustrated and described is the preferred form restrict himself to this one form or shape, as
